Investigation and Fundamental Studies of Burn-Out Failures by Soot Fire

Abstract

The exhausted quantity of soots and hydrocarbons from diesel engine have a tendency to increase as the quality of marine fuel oil deteriorates. Their soots are composed by formed soots from gas phase and cenosphere (such as residual carbon), stick to the surface of exhaust gas economizer, and prevent the heat transfer rate for soot diposits. The heat transfer pipe may occur the heavy damage for oxidation of soot deposits (soot fire), and melt for high temperature.
It is important to be the basic researches on soot oxidation of fin surface.
This studies become the principal experiments on the combustion state of soot pellicle on the fin surface, and on the changes in quality of fin surface with combustion.
